Physical Switch not triggering Rule Machine

I've got a bit of an issue with my smart switches not registering physical switch events. I've had a look at the 'type' column in the events log and there is nothing registering - when it's done through the app it registers as 'command' but the physical switch events just register as blank.

Any ideas what could be causing this?

Thanks

What switches are we talking about? Are they ZWave and not ZWave+ perhaps?

Hi - they are all Zigbee devices.

Not all switches support physical switch events vs digital. And not all drivers support it either. What type of Zigbee devices are these?
